from http://geojson.org/geojson-spec.html " A GeoJSON object with the type "Feature" is a feature object.
A feature object must have a member with the name "geometry". The value of the geometry member is a geometry object as defined above or a JSON null value. A feature object must have a member with the name "properties". The value of the properties member is an object (any JSON object or a JSON null value). " so that means "properties": null which validates on http://geojsonlint.com/ will fix it, did you came across a parser that did not like OJ generated GeoJSON because of that? ..ede On 15.11.2016 09:57, Rahkonen Jukka (MML) wrote: > Hi, > > In GeoJSON FeatureCollection must have "properties" member even if there are > no attributes.
